If you are trying out the various features and functions of your wireless network, you may wonder what is a DNS address on a router. The best routers, after all, all include a DNS address. But what are they and what do they do? Keep reading to find out.
The Domain Name System (DNS) converts domain names into valid IP addresses for all of your connected devices. In other words, a DNS server is a fairly vital part of your Internet connection. By default, your router will go through your modem to your Internet service provider (ISP) to connect to a DNS server, but you can make a change to this process and the steps aren’t too confusing, in line with learning how to change NAT type on a router, or enabling DHCP on a router, or knowing how to port forward a router.
In addition to paid third-party DNS server farms, there are also plenty of free options.
Here are the basic steps to change your router’s DNS server. You can also follow these steps to learn how to close a router port and perform other troubleshooting steps.
The major reason to change up your DNS server is to speed up your Internet connection, especially if you have been experiencing a sluggish connection with your current setup. The default DNS servers supplied by ISPs are not always the fastest when it comes to handing out IP addresses to your connected devices. Also, a third-party DNS service can provide increased wireless network safety. As a warning, however, accessing a DNS service does cost some money, so be prepared to make a purchase.
How can I find my current DNS servers?
Check the DNS settings on your router via mobile device or the admin panel/settings adjustments page. It will show you your default DNS server and any secondary servers.
How can I switch DNS servers?
You do this in your settings via mobile device or a computer web browser. Once you access the router control panel, look for DNS settings or DNS server settings.
When to change DNS servers?
Change DNS server settings if your Internet connection is sluggish or if your wireless network feels unsafe.
STAT: DNS is the Internet’s primary address book. DNS directs traffic to websites and email to your inbox by mapping a domain name you can remember, like google.com, to an IPv4 address such as 184.108.40.206. For all practical purposes, every time you do something on the Internet, you start by invisibly interacting with DNS. (source)
